Should a backend developer learn Javascript?

I’ve been working with static-typed languages for several years now, C# / Java / Scala developer and I like the safety and guarantees of having type checking, also the whole JVM ecosystem aged well with great building tools, libraries and lots of experience from the community. But I cannot ignore all the buzz around Javascript and I don’t want to be prejudiced about something I didn’t work directly for several years.

This is a very overdue blog post that I had on draft for almost an year, but I believe it is still very relevant yet.

A data science toolkit inside a docker image, build it once, run everywhere

If you never heard about Jupyter Notebook, I highly recommend you to check it out. It have been my primary platform to build reports and data driven case studies. On this post I’d like to show how I create a simple and isolated environment with a Bash script and Docker to run JupyterLab. Recently Jupyter Notebook received a major overhauling and become JupyterLab - currently in beta, but the new platform looks fresh and very powerful. Continue Reading »

Where to Find Datasets to Learn Big Data & Data Science

Sometimes you just need data to learn how a algorithm works, to run a stress test or just to have a excuse to spin up several machines in a cluster and see how it crush the data. More often than not, it is incredibly hard to obtain data, and a few colleagues I’ve talked about had similar problem, so this post is a collection of links and references for datasets I know have been open source. Please contribute =)
